tmux bash script create new windows

Code:

#!/bin/bash
sn=test_windows_session_2
tmux new-session -s "$sn" -d

for i in {1..10};  do
        tmux new-window -t "$sn:$i"
done

for i in {1..10} ; do
        for k in carcasper caspats cashpats casblob cashblob cascore cashcore casrash cashrash
        do
        tmux send-keys -t "$sn:$i" "ssh -l casper $k"
        done
sleep 1
done

It creates the windows real good

Code:

                                                                        0: bash  [218x132] (1 panes)
  1: bash  [218x132] (1 panes)
  2: bash  [218x132] (1 panes)
  3: bash  [218x132] (1 panes)
  4: bash  [218x132] (1 panes)
  5: bash  [218x132] (1 panes)
  6: bash  [218x132] (1 panes)
  7: bash  [218x132] (1 panes)
  8: bash  [218x132] (1 panes)
  9: bash- [218x132] (1 panes)
  10: bash* [218x132] (1 panes)

but this was in each pane

Code:

casper@casper:~/script_tmux $ ssh -l casper carcasperssh -l casper caspatsssh -l casper cashpatsssh -l casper casblobssh -l casper cashblobssh -l casper cascoressh -l casper cashcoressh -l casper casrashssh -l casper cashrashbjoh cashpatsssh -l casper casblobssh -l casper cashblobssh -l casper carcas

All I need is a loop that will send keys to each window that i create

Code:

tmux send-keys -t "name_of_session:<increment by one>" "ssh -l waljoh <the_host_to_ssh_to>"
next host

Hi.

What are you trying to achieve? It looks like you want to run few interactive ssh sessions in a row in each pane. How is this supposed to work? Anyway, the only way to execute shell command in a specific pane I managed to find is either to use `shell-command' option to `new-window' or set `default-command':

Code:

#!/bin/bash
sn=test_windows_session_2
tmux new-session -s "$sn" -d
tmux set-option -s default-command 'for k in carcasper caspats cashpats casblob; do PS1="$k: " sh; done'

for i in {1..3};  do
        tmux new-window -t "$sn:$i"
done

I use `sh' instead of `ssh' in this example and set prompt to the name of the host we are supposed to connect to. Type Control-D (or `exit') multiple times and see what happens. Is that what you want?

I was thinking of this on the way home - I need an array.
the number of $i is going to corelate to a tmux window and a separate host - so when

I attach to the session, each windows is going to be ssh'd to a separate host 9one
of the hosts in the array)
i will try thi sout tomorrow when I get to work.

Code:

#!/bin/bash
sn=test_windows_session_4
tmux new-session -s "$sn" -d

for i in {1..10};  do
        tmux new-window -t "$sn:$i"
done
declare -a hosts=('casperutil' 'casperpats' 'casperpats' 'casperblob' 'casperblob' 'caspercore' 
'caspercore' 'casperrash' 'casperrash')

for i in {1..10} ; do
        tmux send-keys -t "$sn:$i" "ssh -l casper ${hosts[$i]}"
        sleep 5
done

if you don't use tmux - it is like linux screen, but scriptable
